In the adhesive-bonded fabric disposable product, when estimating high shear and high when peeling off the lower bonding strength of service condition, have the hot-melt adhesive composition based on polybutene of following constituent content, compare with the hotmelt of prior art and have advantage. More specifically, based on the gross weight of composition, this adhesive composition contains polybutene homopolymers or the copolymer of 15～65 % by weight of having an appointment. The minimum content of polybutylene polymer should be about 15 % by weight in the composition. According to final use and desired properties, can not have polyolefin component, but typically, its content is about 0～70 % by weight. Hotmelt of the present invention also contains the stabilizing agent of 0.01～3 % by weight of having an appointment, and according to final use and desired properties, also selectively contains 0～60% the tackifying resin of having an appointment, the plasticizer of about 0～30 % by weight, or the wax of about 0～20 % by weight. Each component must consist of 100 % by weight of composition, and percentage described here is based on the weight of whole adhesive composition yet significantly.
In thermoplastic hot melt adhesive composition of the present invention, using polybutene component is for the bonding connection intensity that improves material under higher temperature, particularly makes composition have high-peeling strength and high shear strength. Terminology used here " polybutylene polymer " refers to contain ethene and butene monomers, and butene monomer units consists of those polymer of at least 89% of copolymer. Suitable commercially available butene-1-ethylene copolymer can be from Shell Chemical Company of Houston, Texas, bought with trade name Duraflex 8910PC or Duraflex 8510, perhaps suitable homopolymers is DP 0800, also can buy from Shell Chemical Company. The DSC fusing point of preferred material is about 90 ℃ or higher. Based on the gross weight of composition, although the amount of spendable polybutylene polymer is 15～65 % by weight, its preferred use amount is 20～50 % by weight.
Be applicable to that butene-1 homopolymers of the present invention and copolymer are ethyl side groups molecule regular union space ordered arrangement, that be mainly straight chain.

Suitable copolymer can be from Huls America with trade name " Vestoplas ", or has bought with trade name " Rextac " from Rexene Products. Preferred softening point is about 100～160 ℃ copolymer. Should be realized that any mixture of above-mentioned copolymer also can be used as matrix component in composition of the present invention. The effect of polyolefin polymer is to help to provide cementability at no pore matrix. Based on the gross weight of composition, although the use amount of polyolefin polymer can be 0～70 % by weight, preferred amount is 20～40 % by weight.
Should be noted in the discussion above that the mixture that also can use polybutylene polymer and polyolefin polymer, condition is to have used the polybutylene polymer of q.s to give peeling off and shear strength of adhesive composition aequum. The minimized content of polybutylene polymer should be about 15% in the composition. Yet according to final use, and as aforementioned range was pointed, polyolefin component can not exist in composition fully.
The tackifying resin that is used for hot melt structure adhesive of the present invention is to strengthen bond properties and improve polybutene copolymer and/or the material of the specific adhesion of poly alpha olefin copolymer. Terminology used here " tackifying resin " comprising:

As mentioned above, the amount that is applicable to the tackifying resin in the scope of the invention accounts for the about 0～60% of whole composition weights, and when it was used in the composition, its content was preferably about 10～30% of composition weight. Preferably, tackifying resin is selected from any nonpolar type that can buy. The example that is applicable to tackifying resin of the present invention that can buy comprises the commercial resin that is indicated by trade name Escorez, and it is produced by Exxon Chemical Company. Can be used for resin that another kind of the present invention can buy and be the resin of the commodity " Eastotac " by name that can buy from Eastman Chemical Company. Usually, be applicable to nonpolar tackifying resin of the present invention, comprise partially or completely hydrogenation, based on C9Or C5Hydrocarbon, softening point range is about 10～125 ℃ resin. Can be used for tackifying resin of the present invention and also can comprise the polarity tackifying resin. Yet because many polar resins are only partly compatible with butene-1 homopolymers and copolymer, therefore the selection of utilizable polar resin is limited.
For the control of required viscosity is provided, also selectively comprise plasticizer in the composition of the present invention, based on the weight of whole composition, its amount is preferably about 5～15% for about 0～30%. Suitable plasticizer not only comprises plasticizer oil commonly used, such as mineral oil, also comprise olefin oligomer and low-molecular weight polymer (as molecular weight be 2000 or littler low-molecular-weight polybutene), and the derivative of vegetable oil and animal oil and this class oil. Spendable petroleum derived oils is for only containing the relatively high boiling material of a small amount of aromatic hydrocarbons. Based on this point, aromatic hydrocarbons should preferably less than 30% of weight of oil, be more preferably less than 15 %. Or this oil can be does not have aromatic hydrocarbons fully. Oligomer can be that mean molecule quantity is about 350～10000 polypropylene, polybutene, the polyisoprene of hydrogenation, the polybutadiene of hydrogenation etc. Suitable vegetable oil and animal oil comprise glyceride and the polymerizate thereof of aliphatic acid commonly used. Be applicable to that plasticizer of the present invention can be many different plasticizer, but the inventor finds, containing just like the monoolefine polymer that can buy commodity Indopol H-100 by name (it is the monoolefine polymer based on butylene of being produced by Amoco company) and its molecular weight is 2000 or lower plasticizer, is specially adapted to the present invention. As is understood, typically, the use of plasticizer is in order to reduce the viscosity of whole adhesive composition, and does not basically reduce the serviceability temperature of adhesive. Yet if used plasticizer in the composition, the use amount that must increase polybutene keeps the required high-peeling strength of these adhesives with the compensation plasticizer.
Can 0～20 % by weight, the consumption of preferred 5～20 % by weight is used for the wax of the present composition, under the prerequisite of not obvious reduction polymer adhesive feature, can be used to reduce the melt viscosity of hot melt structure adhesive. Under the prerequisite that does not affect temperature performance, these can also be used to reduce the die sinking time (open time) of composition. The wax that is suitable for is:
(1) molecular weight is 1000～6000 low molecular weight polyethylene, and its hardness number of being measured by the method for ASTM D-1321 is about 0.1～120, and the ASTM softening point is about 66～121 ℃ (150～250 °F);

(3) ring and ball softening point is about 120～160 ℃ random polypropylene;
(4) synthetic wax that obtains of the polymerization by carbon monoxide and hydrogen is such as Fischer-Tropsch wax; With
(5) polyolefin-wax. Terminology used here " polyolefin-wax " refers to those polymer or the long-chain material that are made of olefin monomer unit such as ethene or propylene. These materials can be from Eastman Chemical Co., and " Epolene " bought with trade name. Being preferred for the ring and ball softening point that this class material in the present composition has is 93～177 ℃ (200～350 °F). Should be understood that each in these wax dilutions at room temperature is solid. Other this class material that is suitable for comprises animal, fish and plant fat and the oil of hydrogenation, such as the tallow of hydrogenation, lard, soya-bean oil, cotton seed oil, castor oil, pilchardine, cod-liver oil etc., owing to be hydrogenated them and be at ambient temperature solid, finds that above-mentioned these also are suitable for to do the alternative of wax dilution. The material of these hydrogenations often is called " animal or plant wax " in adhesives industry.
Comprise stabilizing agent among the present invention, its consumption is about 0.1～3 % by weight, but is preferably about 0.1～1 % by weight. Be used in combination the stabilizing agent that is applicable to hot-melt adhesive composition of the present invention; help to protect above-mentioned polymer and total adhesive composition; avoid it to be subjected to the common heat that in adhesive production and use procedure, takes place and the impact of oxidative degradation, and final products are exposed to the impact of surrounding environment usually. This degraded usually variation of outward appearance, physical property and the operating characteristic by adhesive shows. The stabilizing agent that is suitable for is hindered phenol and the polyfunctional phenol of HMW, as contains the phenol of sulphur and phosphorus. Hindered phenol is known to the one skilled in the art, it is characterized in that at the phenolic compound that also contains the bigger group of spatial volume near the position of phenolic hydroxyl group. Particularly, usually replace at least one ortho position of the phenolic hydroxyl group of phenyl ring the tert-butyl group is arranged. The effect that reduces its elongation frequency has been played in the existence of the substituted radical that near these spatial volumes hydroxyl are bigger, and has therefore reduced its reactivity; Therefore this sterically hindered effect makes phenolic compound have stability. The representative example of sterically hindered phenol comprises:
1,3,5-trimethyl-2,4,6-three (3,5-di-tert-butyl-4-hydroxyl benzyl) benzene;
